ABSTRACT
Arousal evoked by detecting a performance error may provide a mechanism by which error detection leads to either adaptive or maladaptive changes in attention and performance. By pairing EEG data acquisition with simultaneous measurements of pupil diameter, which is thought to reflect norepinephrinergic arousal, this study tested whether transient changes in EEG oscillations in the alpha frequency range (8-12 Hz) following performance mistakes may reflect error-evoked arousal. In the inter-trial interval following performance mistakes (approximately 8% of trials), pupil diameter increased and EEG alpha power decreased, compared to the inter-trial interval following correct responses. Moreover when trials were binned based on pupil diameter on a within-subjects basis, trials with greater pupil diameter were associated with lower EEG alpha power during the inter-trial interval. This pattern of association suggests that error-related alpha suppression, like pupil dilation, reflects arousal in response to error commission. Errors were also followed by worse next-trial performance, implying that error-evoked arousal may not always be beneficial for adaptive control.
